Remove GdaServerOperation from public API and add interface for DDL operations
I started removing
GdaServerOperation from the public API and I found that all DB objects share the same behavior with regard to DDL operation. I put together a matrix that allows visualizing object and operation relationship.
I think it would be wise to have a generic interface for the mentioned DDL operations and call this interface something like
GdaDDLOperation. For other operations, e.g.
ADD for TABLE we can return a value that will allow identifying if the implementation is not needed. It is not an error, but user can check if the implementation is not required. I opened this issue to discuss this and make sure I didn't miss something.
